2 Claims.

This invention relates to swings and the primary object of the invention is to provide a unique structure for the swing so that the occupant thereof is provided With an up and down as well as a back and forth motion in addition to the conventional swing motion of the swing.

An object of the invention is to provide a swing that gives a lift and then a drop motion to the occupant during the swinging motion, and the swing being operated by the change of weight and direction of swing of the occupant.

With the above and other objects and advantages in View, the invention consists of the novel details of construction, arrangement and combination of parts more fully hereinafter described, claimed and illustrated in the accompanying drawings in which:

Figure 1 is a perspective view of an embodiment of the invention; A

Figure 2 is an elevational view partly broken away of the device;

Figure 3 is a transverse sectional view of the outer bearing supports;

Figure 4 is a transverse -sectional view of the intermediate bearing support;

Figure 5 is an elevational view partly in section of the L-shaped link or supporting arm for the swing and Figure 6 is a sectional view of Figure 5 at the bearing end of the arm.

Referring more in detail to the drawings, the reference numeral I designates generally the swing which comprises a series of vertically disposed standards II which are set in blocks of concrete I2 Which are embedded in the ground I3.

'I'he standards are provided with angular braces I4 which extend downwardly in inclined relation to the standards in opposed relation to each other, to be set in concrete blocks l which are embedded in the ground I3.

Each of the standards is provided at the top on each of the opposite outer faces thereof with a bearing housing I6 having an annular flange I1 which is secured to the respective standard by means of screws I8. Mounted in each housing I6 are the ball bearings I9 in which are j ournalled the alining sections 20 of the crank-shaft 2|. The crank-shaft is tubular in cross-section, and is provided with opposed cranks 22 which are connected to the sections 20 by elbows 23.

To protect the outer ball bearings I9, the housings are provided with caps 24 each having an annular flange 25 which is secured to a housing by bolts 26. The intermediate bearings I9 are protected by apertured caps 21 having an annular ange 28 secured to the housings by bolts 29, and gaskets 30 in the caps prevent moisture from entering the housings and retain the lubricant therein for the bearings.

Each of the sections 20 is provided with a bearing retainer 3I which is threadably mounted thereon, which retain the bearings I9 in proper position in their respective housings in abutment with the shoulders 32 formed on the sections 20.

The cranks are oiset from each other to give a double throw to the swings during the swinging motion thereof.

The cranks have L-shaped links 33 rotatably mounted thereon by means of the bearing ends 34 thereon. The ends 34 are sectional, and provided Wth ears 35 which, secured by bolts 36, permit the mounting of the ends on the cranks, and bearings 31 in the ends 34 freely mount the L- shaped links 33 on the cranks 22. Apertured caps 38 having each an annular flange 39 are secured to the ends 34 by bolts 40, and gaskets 4I in the caps 35 prevent moisture from entering the housings and retain the lubricant for the bearings therein. The caps also retain the bearings in abutment with the shoulders 42 formed in the ends 34 and the ends being mounted in the grooves 43 in the cranks 22 retain the bearings in abutment with the shoulders 44 formed on the cranks 22.

The ends of the L-shaped links 33 opposite to the ends 34 are apertured at 45 to receive theA looped ends 46y of the swing seat Supporting ropes 41 which are secured at their opposite ends to the swing seats 48 by the conventional knots 49.

In operation, the occupants of the swing are given a motion by the throw of the cranks, and the various positions of the L-shaped links; thus an up and down motion is conveyed to the seats 48.

It is believed that from the foregoing description, the operation and construction of the invention will be apparent to those skilled in the art, and it is to be understood that changes in the minor details of construction, arrangement and combination of parts may be resorted to, provided they fall within the spirit of the invention and the scope of the appended claims.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent is:

l. A device of the character described, comprising vertically positioned relatively spaced supports, bearings in the upper ends of said supports,

a shaft having opposed cranks therein and jour- 2,548,375 3 4 nalled in said bearings, L -shaped links secured to REFERENCES CITED said cranks and swing supporting ropes secured The f n f r to said L-shaped links the offset cranks giving an me of tsvgrfferences are o reco d m the up and down movement to said supporting ropes during the swinging movement/of said swing. 5 UNITED STATES PATENTS 2.
